Summary
This paper describes a new encryption method called FDXT that helps protect data privacy when searching encrypted files on untrusted servers. Previous methods like ODXT and SDSSE-CQ had weaknesses where attackers could leak information by analyzing search patterns and file sizes when users searched for multiple keywords together, but FDXT fixes these privacy leaks while maintaining similar or better performance.
